Optimized Trend Tracker OTT indicator

tarantula3535 commented 4 years ago

hi i want to write this indicator in python but i dont have much time.. here is the tradingview's url https://tr.tradingview.com/script/zVhoDQME/ this indicator is very helpfull the filtering in the buy signals conditions.. I would be glad if you could write this indicator in Python

Hi ! I would also be very interested to have this OTT indicator integrated into Freqtrade.

tarantula3535 commented 4 years ago

and also this indicator.. https://tr.tradingview.com/script/sU9molfV/ Pmax profit maximizer can anyone write this code and implement in it the freqtrade?

tarantula3535 commented 4 years ago

If I can take a little time out, it's like I figured out the logic. It can be solved by something like adding a moving average to Supertrend.

tarantula3535 commented 4 years ago

in the OTT If the calculations compare correctly with tradingview, different results come out.. I could not find the reason for this.. e.g. ARDR USDT

xmatthias commented 4 years ago

Interresting the point i'm not confident is the dir calculation.

    # dir = 1
    # dir := nz(dir[1], dir)
    # dir := dir == -1 and Var > shortStopPrev ? 1 : dir == 1 and Var < longStopPrev ? -1 : dir

In my understanding, dir will be assigned 1 - will be assigned to all rows with 1 by using the previous row - making the comparisons to dir below (if it's 1 or -1) irrelevant.

Might be this should be calculated in a loop - but i'm not sure if that's how pinescript does it.

tarantula3535 commented 4 years ago

i couldnt find the bug where is... some pairs work correctly..some pairs not..

xmatthias commented 4 years ago

One big problem with these indicators is always the starting point (this is fully based on the result of the previous row - so a change 2000 lines ago will (very slightly) change the result in the last candle. It's usually not visible as it's in the 10th decimal place (or wherever) - but slight change nonetheless.

Obviously, this error will then depend on the price of the coin (a coin priced 0.00005 is more likely to have a "visible" error than one priced 200.05)...

It should however be similar with other indicators as well (like VIDYA) - which also has a similar calculation

tarantula3535 commented 3 years ago

@xmatthias you right that... Pmax is also an indicator that works well.... you should take a look at it too

Cuzeppe commented 3 years ago

Hi @tarantula3535 I'm a newbie and don't know how to add this indicator. but my favorite indicator on tradingview is pmax. Is there any documentation that explains how to do this?

when i try to download "technical" from git it downloads all the files into .local/lib/python3.8/site-packages am i doing something wrong?

if you don't use virtual env , you are doing right..

when i try to download "technical" from git it downloads all the files into .local/lib/python3.8/site-packages am i doing something wrong? i am copy and paste the function in this file... technical-->indicator-->indcators.py and call in the strategy file just like that..

tarantula3535 commented 3 years ago

this is the definition.. How you use it is up to you... for example ema cross pmax value --> You can use it as in the populate_buy_trend

(qtpylib.crossed_above(dataframe[mavalue] , dataframe[f'pm_{pmaxperiod}_{pmaxmulti}_{pmaxl}_{pmaxtype}']))

then leave it open ... otherwise it'll "disappear" into the "closed issues" list ... and unless i explicitly remember (which i probably won't) - it'll not be added. on the other hand, nothing prevents you from attempting a Pull request adding this :) it's no magic... :)

I am trying to write the same code in R without much Pinescript knowledge. https://www.tradingview.com/pine-script-docs/en/v4/Quickstart_guide.html#execution-model-of-pine-scripts

Pine script seems to be running recuvrsively or similar to a loop.

I think below code gives something similar for the dir part. Maybe it needs a lag here and there but basically, what it does is if there is a change in dir, for all the next values it is also changed.

`for(i in 1:maxNo) {

if(dir[i] == -1 & MAvg[i]>shortStopPrev[i] ){ dir[i] <- 1 dir[i:maxNo] <- 1 } else if(dir[i] == 1 & MAvg[i]<longStopPrev[i]){ dir[i:maxNo] <- -1

}

Thank you, I'll give it a try. What is exactly maxNo? Is it the period of OTT?

rafadan2 commented 3 years ago

I used maxNo for the number of bars, or how long the data is. So the loop iterates from the beginning until maxNo(end of data).

ysdede commented 3 years ago

Hi, I came on this site while looking for an OTT indicator in Python, thanks to @tarantula3535 for inspiring me with his efforts. I've built a Numpy/Numba-based version as well. At the time, just VAR is supported (EDIT: I've added Kaufman's Adaptive Moving Average (KAMA) and WMA), but adding ta-lib moving averages is straightforward. You can use it with freqtrade or the other frameworks relies on Pandas dataframe by converting pandas dfs to numpy array and vice versa. You can disable, remove, or install the part that uses Jesse's split tool. Var indicator is currently incompatible with Numba and performs slowly, but it works; I've validated OTT output with Tradingview version. custom_indicators Suggestions and pull requests are welcome.

Don't these implementations lookahead?

no - not because of this, anyway - this is simply a loop accessing all columns. It would lookahead if you'd use a "total" (or last row) within the loop - but it doesn't, only access is to i and i-1

svsvfx commented 2 years ago

Hello everyone, first of all thx for OTT and Pmax indicator. But I used for backtest I need Kıvanç Özbilic's Stochastic OTT. https://tr.tradingview.com/script/BK45kYNB-Stochastic-OTT/

This indicator works great for 1m charts. I'm not good for programing but i tired few things but when I try to smooting stochastic %K with "vidya" it's return NaN. I'm used pandas_ta library. Here is my simple code;

periodK = 600 period_d = 33 smoothK = 500

"""for stoch %K with vidya" df["stoch"] = df.ta.stoch(k=periodK,d=period_d,smoothk=smoothK, mamode = "vidya")[f"STOCHk{periodK}_{periodd}{smoothK}"]

"""for smooting %K with vidya" df["k"] = ta.ma("vidya", source = df["stoch"], length = smoothK)

and df["k"] return NaN all time.
Thanks for helping.

Is there any one who tested this ?

Hello everyone, first of all thx for OTT and Pmax indicator. But I used for backtest I need Kıvanç Özbilic's Stochastic OTT. https://tr.tradingview.com/script/BK45kYNB-Stochastic-OTT/

This indicator works great for 1m charts. I'm not good for programing but i tired few things but when I try to smooting stochastic %K with "vidya" it's return NaN. I'm used pandas_ta library. Here is my simple code;

periodK = 600 period_d = 33 smoothK = 500

"""for stoch %K with vidya" df["stoch"] = df.ta.stoch(k=periodK,d=period_d,smoothk=smoothK, mamode = "vidya")[f"STOCHk{periodK}_{periodd}{smoothK}"]

"""for smooting %K with vidya" df["k"] = ta.ma("vidya", source = df["stoch"], length = smoothK)

and df["k"] return NaN all time. Thanks for helping.

Hi any progress on this or is there somebody who can adjust the OTT to SOTT indicator?

dpanday77 commented 2 years ago

@mata1234 When i print out the df of OTT and Var then the values are not the same as with TV. I tested several settings by changing the pds and percent variables. Also when using another timeframe. Maybe you can have a look at it. Besides that i wonder if you are able to convert this indicator as well: https://www.tradingview.com/script/BK45kYNB-Stochastic-OTT/

froggleston commented 2 years ago

TV indicators might well not be the same as other TA libraries so you probably will see different results for more complex calculations.

ahmedevv commented 1 year ago

If you guys haven't figured out the OTT indicator in Python then I've implemented it a few weeks back in my BOT which is working with SuperTrend, ADX, EMA and OTT. I can give you guys the implementation of OTT. Let me know if I can be of any help.

@ahmedevv I'm interested on how you have implemented the indicator and also which version because the ones i have used doesn't match exactly with the values of Tradingview

i use in the strategy just like that...i hopefully helped you.. e.g. trend is "up" look other indicators... e.g. ema crossover pmax value..

Hi guys! can someone explain why in PMAX for loop starting from ATR period instead of 1? for i in range(period, len(df)):

xmatthias commented 1 year ago

Hi guys! can someone explain why in PMAX for loop starting from ATR period instead of 1? for i in range(period, len(df)):

most likely, because ATR will be empty (NaN) for the first period candles. This makes all calculations based off of it either NaN or wrong. starting from period is a micro-optimization (it'll avoid a few loops) - but not doing it would be pointless, too.
